Answer 1

its your answer my friend

Answer 2

Answer:

x=20

Step-by-step explanation:

in ascending order 8,11,13,15,x+1,x+3,35,40,43

n(total number of observation)

n=10(Even)

median=1/2{(n/2)th observation+(n/2+1)th observation}

22=1/2{10/2)th observation+(10/2+1)th obs}

22=1/2{5th obs + 6th obs}

22=1/2{x+1+ x+3}

22=2x+4/2

22*2=2x+4

44=2x+4

2x=44-4

2x=40

x=40/2

x=20
